Medians are one of the most important set of elements related to a triangle. The symmetry associated with the medians give rise to a rich set of concepts and relations. In addition to a number of important area related concepts, we will discuss here how to find the area of a triangle from the given length of its medians...

Medians form one of the most important set of components in a triangle closely tied to the triangle independent of any other geometric shape. In this discussion we will explain what are medians and their relations with the sides of the triangle along with the proofs...

Sometimes in the breakneck hurry while struggling with the questions in a cutting edge leading selection test you might meet a problem that doesn't seem right somehow. You figure out the only way to arrive at the solution but out of sheer curiosity you check back the solution value with the given values to verify the sanctity of the problem definition...

To explain the Arc angle subtending concept exhaustively and comprehensively, we will use four different configurations and the corresponding mechanisms along with solving a specially selected problem. To be exhaustive, we needed to follow a systematic method...

Time and distance problems are taught in middle schools and also form an important component of competitive tests. In this second session of time and distance problem solving in a few steps, we have shown the process of reaching solution in a few steps for two chosen problems...

Basic Geometry concepts with general problem solving strategies and techniques produce elegant solutions in difficult Geometry problems just as in Algebra or Profit and loss. In this third session of Geometry problem solving in a few steps we will analyze solution process of three chosen geometry problems...

Applying Basic Geometry concepts together with general problem solving strategies and techniques produce elegant solutions in difficult Geometry problems just as in Algebra or Profit and loss. In this second episode of Geometry problem solving in a few steps we will analyze solution process of four chosen geometry problems...

Geometry is no different from Algebra or Profit and loss with respect to solving a difficult SSC CGL problem in a few steps by applying Basic subject concepts together with Problem solving strategies and techniques. In this first episode of Geometry problem solving in a few steps we will analyze solution process of two chosen geometry problems...

Traveling at same speed we would need twice the time we took last time, if we have to cover twice the distance we traveled last time. This follows from our common sense. The relationship between speed, time and distance is one of the most basic physical laws that affects our real life experiences extensively. Trains run from station to station at various speeds; boats ply in the river but their actual speeds are reduced by the river stream speed if the boat moves upstream...the applications of the relationship between speed time and distance form an important part of Arithmetic...

Usually profit and loss problems do not come difficult, variations are few and with a bit of grounding on concepts you can solve any of this category of problems easily. That's why this one surprised us. At the first glance there seemed to be too many variables and the problem unsolvable. But when we looked deeper we discovered the clues to elegant solution one by one...
